Hastelloy X is a wrought nickel base alloy with excellent high temperature strength and oxidation resistance. All of the product forms are excellent in terms of forming and welding. Although Hastelloy X is primarily noted for heat and oxidation resistance it also has good resistance to chloride stress-corrosion cracking and has good resistance to carburization, excellent resistance to reducing or carburizing atmospheres. Alloy X is one of the most widely used nickel base superalloys for gas turbine engine components. Hastelloy X has no yield or tensile strength requirements, but it does require a hardness maximum and stress rupture minimums. Strong and Oxidation Resistant to 2200 Deg. F (1200 Deg. C) - Hastelloy X is a solid solution strengthened grade has good strength and oxidation resistance up to 2200 Deg. F (1200 Deg. C).
Hastelloy X also resists carburization and nitriding, two common conditions which often lead to early failure in high-temperature alloys. After 100 hours in petroleum coke, four other materials were completely penetrated by carburization; whereas, Alloy X specimens showed no carburization at all. Of ten materials evaluated in an atmosphere of hydrogen, nitrogen and ammonia at 1100 Deg. F. and 25,00 psi for 64 days, Alloy X had a nitride case less than one-fourth as thick as the closest competitive material without intergranular attack.
Alloy X materials can be cold rolled to various tempers. It cannot be hardened through heat treating. It is easily fabricated. Alloy X maintains excellent corrosion resistance. It is readily formed by cold-working. Hastelloy X are stronger at metal cutting temperatures than other materials. Machining of nickel alloys such as Alloy X requires tooling that minimizes cutting forces with maximum edge strength. This alloy exhibits good ductility after prolonged temperatures up to 1600°.
JN Alloy is suppliers of Hastelloy X nickel in pipe, sheet, flange, fittings, round bar, and plate stock in a variety of lengths and widths, and we can custom cut this material to your exact specifications. Our products can also be slit to your desired width.

Hastelloy X is a nickel-based superalloy renowned for its high-temperature strength and exceptional oxidation resistance. It comprises Nickel (Ni) as its base element, along with approximately 22% Chromium (Cr) for oxidation resistance, Molybdenum (Mo) for strength and corrosion resistance, Cobalt (Co) for high-temperature stability, and Tungsten (W) for enhanced strength and hardness. It also includes controlled amounts of Iron (Fe), Aluminum (Al), Titanium (Ti), Boron (B), Carbon (C), Manganese (Mn), Silicon (Si), Phosphorus (P), Sulfur (S), and Copper (Cu) to fine-tune its properties.
Hastelloy X is widely used in the aerospace industry for its superior strength and corrosion resistance at high temperatures. Key components made from Hastelloy X include jet engine parts like combustion chambers, afterburners, transition ducts, combustor cans, spray bars, and flame holders, thanks to its ability to withstand extreme temperatures and oxidative environments. It is also used to make aircraft engine blades, nozzles, rocket thrusters, and other propulsion parts, ensuring reliable performance in tough conditions.
In the petrochemical and chemical processing industries, Hastelloy X is essential because it resists oxidation, carburization, and chloride stress corrosion cracking. Components like retorts, muffles, catalyst support grids, furnace baffles, and pyrolysis tubing are often made from Hastelloy X, ensuring the longevity and safety of critical processing equipment in harsh environments.
In the nuclear power industry, Hastelloy X is used for its stability at high temperatures and corrosion resistance, particularly in making parts for gas-cooled reactors and heat units. The alloy’s ability to maintain mechanical integrity under high thermal stress is crucial for the safe and efficient operation of nuclear power plants. Hastelloy X is also used in nuclear fuel element cladding, providing a robust barrier against radiation and chemical attack.
In the automotive sector, Hastelloy X is used for high-performance and high-temperature parts like turbochargers, exhaust valves, and other exhaust components, benefiting from its strength and corrosion resistance. The material’s durability under thermal cycling conditions ensures the reliability and efficiency of automotive engines, especially in turbocharged and high-performance vehicles.
Hastelloy X also excels in other fields thanks to its exceptional properties. In the medical field, it is used for devices and instruments requiring high strength and corrosion resistance. It is also vital in steam turbine power plants for withstanding high temperatures and corrosive environments. Additionally, Hastelloy X is used in the manufacturing of furnace parts, such as furnace rolls and trays, which must operate at elevated temperatures without significant degradation.
Hastelloy X is increasingly used in additive manufacturing processes like laser powder bed fusion (L-PBF) and directed energy deposition (DED) to produce complex, customized components not possible with traditional methods. Using Hastelloy X in additive manufacturing is especially beneficial for aerospace and chemical processing, where intricate designs and high-performance materials are needed, ensuring parts with excellent mechanical properties and high-temperature resistance.
